A new method for gasification of a powdered fuel in filtration regime with continuous injection of fine dust is proposed and tested. The fuel is supplied suspended with the flow of oxidant gas, whereas the gas flow filters through a porous bed of large inert particles making a heat recovery medium. The experiment showed a possibility to enhance efficiency of gasification of solid fuels in filtration regime. The efficiency is enhanced by means of improved throughput of a reactor and production of the gas without a noticeable concentration of pyrolysis tars, which gas, upon cleansing of fly ash is suitable to feed a gas motor.
